The veteran female officer was making a left-hand turn from Hooper Street to Broadway and failed to see the Coss, a teacher at the Beginning with Children Charter School, a source said. Coss was rushed to Bellevue Hospital, where he was pronounced dead.

No criminality and no traffic-law violations are suspected, police said.

Valerie Davis-Fells, assistant principal at the school where Coss taught, said the single man was like her children’s godfather.
